- Purpose: To investigate and describe how persons with an acquired brain injury (ABI) manage everyday technology (ET) in their daily activities and to explore whether the ability to manage ET was related to the severity of the disability. Method: Eighty-one persons with ABI were observed while managing ET by using the Management of Everyday Technology Assessment (META). The Glasgow Outcome Scale-Extended (GOSE) was used to assess the severity of disability after the ABI. A computer application of a Rasch measurement model was used to generate measures of the participants’ ability to manage ET and the measures were compared groupwise with analysis of covariance (ANCOVA). Results: The degree of severity of disability had a significant main effect on the ability to manage ET. The groups with severe and moderate disability exhibited a significantly lower ability to manage ET compared to the group with good recovery. Conclusion: The result indicates that the ability to manage ET in daily activities can be related to the global severity of disability after ABI. This demonstrates the importance of considering the ability to manage ET to support the performance of activities at home, at work and in society in persons with ABI.

- Gain-of-function mutations in the tetrodotoxin (TTX) sensitive voltage-gated sodium channel (Nav) Nav1.7 have been identified as a key mechanism underlying chronic pain in inherited erythromelalgia. Mutations in TTX resistant channels, such as Nav1.8 or Nav1.9, were recently connected with inherited chronic pain syndromes. Here, we investigated the effects of the p.M650K mutation in Nav1.8 in a 53 year old patient with erythromelalgia by micro-neurography and patch-clamp techniques. Recordings of the patient's peripheral nerve fibers showed increased activity dependent slowing (ADS) in CMi and less spontaneous firing compared to a control group of erythromelalgia patients without Nav mutations. To evaluate the impact of the p. M650K mutation on neuronal firing and channel gating, we performed current and voltage-clamp recordings on transfected sensory neurons (DRGs) and neuroblastoma cells. The p. M650K mutation shifted steady-state fast inactivation of Nav1.8 to more hyperpolarized potentials and did not significantly alter any other tested gating behaviors. The AP half-width was significantly broader and the stimulated action potential firing rate was reduced for M650K transfected DRGs compared to WT. We discuss the potential link between enhanced steady state fast inactivation, broader action potential width and the potential physiological consequences.

- The Swedish academic computing landscape is organized under the auspices of SNIC, the Swedish National Infrastructure for Computing. SNIC coordinates investments in computing and storage infrastructure at its six national centers and manages the national process for allocating research time on its computing resources. Since its formation in 2003, SNIC has significantly increased the computational capacity available to Swedish researchers and firmly put Sweden on the international computational science map. When the Partnership for Advanced Computing in Europe (PRACE) started in 2010, SNIC joined this European HPC effort and worked with the Swedish Research 142Council to allocate additional funds for a national high-end system that would also be made available to European researchers via PRACE. These efforts resulted in the installation of a CRAY XE6 supercomputer, named Lindgren, at the PDC Center for High-Performance Computing at the KTH Royal Institute of Technology in Stockholm.
